A valve prosthesis (

9

) for implantation in the body by use of catheter (

11

) comprises a stent made from an expandable cylinder-shaped thread structure (

2,3

) comprising several spaced apices (

4

). The elastically collapsible valve (

6

) is mounted on the stent as the commissural points (

5

) of the valve (

6

) is secured to the projecting apices (

4

).

The valve prosthesis (

9

) can be compressed around the balloon means (

13

) of the balloon catheter (

11

) and be inserted in a channel, for instance in the aorta (

10

). When the valve prosthesis is placed correctly the balloon means (

13

) is inflated thereby expanding the stent and wedging it against the wall of the aorta. The balloon means is provided with beads (

14

) to ensure a steady fastening of the valve prosthesis on the balloon means during insertion and expansion.

The valve prosthesis (

9

) and the balloon catheter (

11

) make it possible to insert a cardiac valve prosthesis without a surgical operation comprising opening the thoracic cavity.
